What is this 'good team' you speak of. I've never heard of such thing.
most people misunderstand winning with kda. You probably did some wrong decisions just as a whole team. You end up losing then. Cause with the right decisions ans choices you could carry. But yes sometimes random people make it tougher to pull off. Just dont call people bad. They might have warded more or did something else better. Besides that this 4-20 person rly had a rough one yes. Better luck next time !
